Ryan Giggs insists Manchester United do not consider themselves underdogs for Tuesday night's Champions League quarter-final showdown with European champions Bayern Munich.

Pep Guardiola's trophy holders meet United at Old Trafford in a match which sees the 1999 finalists go head-to-head once again.

Giggs played in the famous 2-1 triumph in Barcelona 15 years ago and, although Bayern now look to be favourites to progress having won the Bundesliga at a canter while United flounder in the Premier League, he remains confident.

"Obviously Bayern are a fantastic team," the Welsh winger said. "They're the holders and Pep Guardiola's taken over and added a few new players and they're a very strong team.

"They're obviously favourites in most people's eyes but we're Manchester United at Old Trafford and we've seen so many good nights there, in Europe especially.

"So as players we don't see ourselves as underdogs, we see ourselves as Manchester United playing at home in the Champions League.

"We can't wait. These are the games that you want to be involved in as a player.

"We'll go out there and, yes it's going to be tough, but we're confident."

Man Utd v Bayern Munich key battles

Man Utd v Bayern Munich key battles

1/3
Alex Buttner v Arjen Robben

United manager David Moyes has no option but to hand Buttner just his ninth start of the season as first-choice left-back Patrice Evra is suspended. Although Buttner lacks experience at the top level, he is certainly not short of confidence. "I know what Arjen Robben can do and I am ready for him," he said following Saturday's win over Aston Villa. Robben is a pacy, clever winger capable of beating his marker down the flank or cutting inside and firing on goal. He is enjoying the best form of his career at Bayern, for whom he scored the winning goal in last year's Champions League final against Borussia Dortmund.

2/3
Wayne Rooney v Jerome Boateng

Rooney underlined his importance to Manchester United with a brace that turned Saturday's game against Villa on its head. The United striker is starting to reach peak form just as Moyes needs him more than ever. With Robin van Persie out, Rooney will lead the line for United on Tuesday when he will come up against Boateng. The German endured a miserable solitary season for Manchester City, but he has found his feet at Bayern, where he is a first-team regular.

3/3
Nemanja Vidic v Mario Mandzukic

Mandzukic has played a key role in Bayern's title triumph by scoring 17 goals. The striker's position in the team is under threat thanks to the impending arrival of Robert Lewandowski so he will be out to impress at Old Trafford. Vidic wants to end his final season at United with a trophy, but he has shown signs that he is past his best in recent times. Daniel Sturridge and Luis Suarez had little trouble getting past the Serb when Liverpool beat United 3-0 recently.

United boss David Moyes echoed Giggs' optimistic comments and revealed he has been impressed with his players' attitude in training ahead of such a high-profile game.

"We know that on our day we're as good a side as any but we have to show it more often," the Scot said.

"I've got great belief in the players and I've said that from day one - that hasn't changed.

"I get the feeling the players all want to play, I can tell that from their attitude in training.

"They all want to play in the big games, that's what the players here have wanted to do over the years."

Moyes has injury problems in his backline with full-backs Rafael and Alexander Buttner now doubtful to feature while Rio Ferdinand, Chris Smalling and Jonny Evans work their way back to full fitness.

"We have defensive issues, undoubtedly," Moyes added.

"I won't be giving out my team today, certainly not to Bayern or to you (the press), but we will have to make one or two changes."
